Patent CA-1300929-C (CA)
Inventor: MILLS NED
IPC: F16H29/04
Filed: 1988-06-21
Granted: 1992-05-19
Abstract: Abstract A mechanical transmission converts rotational motion of an input drive shaft to an alternating radially directed motion of a selected amplitude. The alternating motion imparts rotational movement to an output driven shaft through imposition of one-way clutches. The alternating radially directed motion is varied by means of a rotatable self-balancing cam assembly. The self-balancing cam assembly includes a working, radially offsettable cam component and a compensating counterbalance. The cam and counterbalance are interconnected by u plurality of eccentric orbital coupling elements which rotate with the input drive shaft and are selectively rotatable thereabout. These impart simultaneous radial movement to the cam and counterbalance as desired to maintain the transmission in a dynamically balanced condition over its full range of operation.

Title: Integrated thermal ink jet printhead and method of manufacture
Inventor: BHASKAR ELDURKAR V
IPC: H01S5/223
Filed: 1988-07-21
Granted: 1992-06-02
Abstract: Abstract We describe an integrated thermal ink jet printhead and manufacturing process therefor which includes the successive build-up of an orifice plate, a first barrier layer, heater resistors, a second barrier layer, and an ink reservoir-defining layer on top of a reusable or "dummy" substrate.  Lead-in conductors are formed integral with the heater resistors by controlling the cross- sectional areas of these components, and openings (passageways) are formed between ink reservoirs and the orifice plate to provide for ink flow under control of the heater resistors.  The dummy substrate is stripped away from the adjacent orifice plate, and the ink reservoir defining layer may be secured to an ink supply tank which supplies ink to the individual ink reservoirs.  Thus, the orifice plate, heater resistors and ink flow paths of the printhead are self aligned, and the heater resistors are removed from direct cavitational forces from ink ejected from the orifice plate.

Title: Adjustable latching device with memory feature for vehicle seat assemblies
Inventor: CROFT GEORGE
IPC: B60N2/235
Filed: 1988-12-28
Granted: 1991-12-31
Abstract: ABSTRACT       This invention provides an improved adjustable latching device for use with a vehicle seat assembly having a first and a second seat member pivotally foldable relative to one another  about  a pivot  axis  between  folded  and  unfolded operative configurations.   The device accommodates both the well-known  "dumping"  and  "reclining"  features  and  is comprised of a latch pin rigidly mounted on the first seat member so as to define a first concentric arc of movement upon said pivotal folding of the first seat member about the pivot axis and an idler plate having a generally arcuate gear sector and being mounted for rotation about the pivot axis. A locking arm is rotatably mounted on the idler plate and presents a detent portion position adjacent one end in spaced relation from the point of rotational movement of the arm so as to be adapted to lockingly engage the latch pin, which locking engagement in turn causes rotation of the idler plate with  the  first  seat  member  in  at  least  one  rotational direction upon pivotal folding of the first seat member.  A first rotational control means for selectively rotating the locking  arm  into  and  out  of  the  aforementioned  locking engagement is also provided.  A pawl means having a head and a tail portion is pivotally mounted on the second seat member intermediate its head and tail portions for pivotal movement between a first rotational position at which the head portion lockingly engages the gear sector to prevent rotation of the idler plate and the second rotational position at which the head portion is disengaged from the gear sector to allow for rotation of the idler plate about the pivot axis.  A second rotational control means for selectively rotating the pawl means between the aforementioned first and second rotational positions  is  also provided.   The  device  disclosed is considerably  simpler  to manufacture  and assemble  than previously known devices having the same features.

The values of absorbance by the sample at multiple wavelengths are measured and the optimum linear combination of absorbance values is determined to obtain a measure of chromophore concentration.  Extinction coefficients for a chromophore is measured employing Deming's method and eigenvector transformations.  A matrix reflecting the noise pattern of the system is determined.  This matrix and the extinction coefficients are used in determining the coefficients for the optimum linear combination.  An electronic module converts analog intensity data into digital data for five wavelengths.  This is processed into absorbance values and concentration determinations.
